Bob Long Technologies Filtered Fill Valve - Silver Replacement Goggle Parts integrated into an interchangeable dualAnother industry first for Bob Long, a self filtered fill nipple! This HPA tank upgrade replaces your current fill nipple. It features a captured piston to prevent overtightening and o ring blowout from filling too fast and a screen filter to keep dirt and metal particles from running through your tank's reg or marker's seals. Hardened material means it doesn't get chewed up from the fill whip's ball bearings, making this smart investment last longer.
